Yes a true dirt bike is the only way to go and have had many Honda dirt bikes in the 48 years of riding, but the CRF450X can be rego, its very powerful, and handles so well in the dirt and will eat dual sport bikes in the dirt.
The Norton I have owned since new and was a everyday rider till I brought my new 2013 900 Thruxton I clocked up over 40k on it without touching it only the maintenance, then the 1200 Thruxton's came along and after a few years walking past the Green Thruxton S at the dealers to get my oil filters I decided to take one out for a test ride which at the time was the Thruxton R, I was stoked in how good they were but I was in love with that 2016 green Thruxton S, because it was old new stock and with the fairing kit fitted the price was dropped by $3.5k and I ask the salesman todays price they dropped another $1k off the price, that was in 2018, so far with over 20k on it but last year this virus with lock downs I didn't do much riding like I normally do stayed home and reno inside my old house, I have my 1200 Thruxton set up for traveling.
